Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM
Are you tired of chasing electrical gremlins in your 2010 Cadillac Escalade or other GM vehicle? Intermittent power windows, flickering lights, strange security system alerts, or a dashboard that lights up with random warnings are all classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated problems. In my 20+ years of diagnostics, I’ve seen how a bad BCM can make a perfectly good vehicle feel unreliable. This isn’t just an inconvenience; it’s a matter of proper function and safety.
Forget the expensive dealership visit and the hassle of post-purchase programming. We offer a direct, effective solution. This Body Control Module, part number 20864767, arrives at your door fully programmed to your vehicle’s specific VIN. We load the latest GM software updates, ensuring optimal performance and compatibility right out of the box. This simple step saves you time, money, and the headache of coordinating with a service center for programming. It’s the smart, efficient way to get your vehicle back to 100%.
A Technician’s Notebook
A customer brought in a 2010 Yukon XL last month with a truly bizarre set of symptoms. The radio would turn on and off by itself, the driver’s side power lock was dead, and the rear wiper had a mind of its own. He had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw multiple communication errors between various modules, all pointing back to one culprit. We installed a VIN-programmed BCM, and like magic, every single issue was resolved. It’s a perfect example of how this single component, the 2010 Escalade BCM, is the true nerve center of the vehicle’s comfort and convenience features.
Your Straightforward BCM Installation Guide
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work. Wait a few minutes to allow the system to fully discharge.
- Locate the BCM: On most compatible vehicles like the 2010 Escalade, Tahoe, and Yukon, the BCM is located under the driver’s side dashboard, near the steering column. For vans like the Express or Savana, it’s often behind the center dash panel. Consult your vehicle’s service manual for the exact location.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New BCM: Mount your new, pre-programmed BCM into the same position. Securely plug in all the electrical connectors, ensuring each one clicks firmly into place.
- Reconnect Power: Reconnect the negative battery terminal and tighten it securely.
- Perform Final Procedures: Start the vehicle. You will need to perform two critical post-installation steps: the ‘Setup SDM Primary Key in BCM’ procedure to clear the airbag light and, if necessary, a Brake Pedal Position Sensor recalibration. These steps require a compatible professional scan tool.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or mirrors operate erratically or not at all.
- ✔ Interior or exterior lights flicker, stay on, or fail to turn on.
- ✔ The vehicle’s security system engages randomly, preventing the car from starting.
- ✔ The horn honks unexpectedly or doesn’t work when needed.
- ✔ Dashboard warning lights (like the airbag light) illuminate for no apparent reason.
- ✔ Communication issues between different electronic modules, leading to various error codes.

Frequently Asked Questions
Do I need to program this BCM?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready for installation, saving you a trip to the dealership.
Where is the BCM located on my 2010 Escalade?
On the 2010 Escalade and similar GM SUVs, the Body Control Module is typically found under the driver’s side of the dashboard, attached near the steering column.
What happens if I don’t perform the post-installation procedures?
Failure to perform the ‘Setup SDM Primary Key’ will result in the airbag warning light staying on. The brake pedal recalibration ensures proper brake light function and stability control performance. These steps are crucial for safety and are not optional.
Is this part difficult for a DIYer to install?
The physical replacement is straightforward for someone with basic mechanical skills. However, the final setup steps require a professional-grade diagnostic scan tool. If you don’t have one, you will need assistance from a qualified mechanic to complete the job.
Will this fix my ‘Service Theft System’ message?
In many cases, yes. The BCM is integral to the Pass-Key/Pass-Lock anti-theft system. A failing BCM is a very common cause of these security-related issues and starting problems.
How do I provide my VIN number?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot program and ship your part without it.
